As of April 1, 2007 Princess has modified the their free internet access perk for Platinum and Elite members. The free access at the Internet Cafe is no longer completely free. From their website:

Free Internet Access
Credit Towards Internet Café Packages (effective April 1, 2007)
$75 for voyages of 7 days or less
$100 for voyages of 8-20 days
$200 for voyages of 21 or more days

I encourage everyone to let Princess know you feeling about this change of policy. It was one of the last remaining perks that really meant something & if enough people complain they might reverse their decision.
